    <li><a href="http://www.qhull.org">Qhull Home Page</a> <p>Qhull
        computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace
        intersection about a point, furthest-site Delaunay
        triangulation, and furthest-site Voronoi diagram. It
        runs in 2-d, 3-d, 4-d, and higher dimensions. It
        implements the Quickhull algorithm for computing the
        convex hull. Qhull handles roundoff errors from floating
        point arithmetic. It can approximate a convex hull. </p>

        Qhull version 1.0</a> (92K) <p>Type: C source code for
        32-bit architectures </p>
        <p>Version 1.0 is a fifth the size of version 2.4. It
        computes convex hulls and Delaunay triangulations. If a
        precision error occurs, it stops with an error message.
        It reports an initialization error for inputs made with
        0/1 coordinates. </p>
        <p>Version 1.0 compiles on a PC with Borland C++ 4.02 for
        Win32 and DOS Power Pack. The options for rbox are
        &quot;bcc32 -WX -w- -O2-e -erbox -lc rbox.c&quot;. The
        options for qhull are the same. [D. Zwick] </p>
